as与which引导定语从句时区别有：意思不同、用法不同以及侧重点不同。
一、意思不同
1、as意思：作为；如同
例句：
They made the same mistake as others would have made on such an occasion.
他们犯了和其他人在这种场合下会犯的同样错误。
2、which意思：哪一个；哪些
例句：
When deep in thought, which he often was, he would forget all around him.
他常常陷入沉思，这时他就会忘掉周围的一切。
二、用法不同
1、as用法：当两个主语的动作是同时发生的时候，主句和从句的谓语动词都可以用进行时态或一般式，无论动作长短；当两件事发生的时间间隔很短，甚至没有时间间隔时，主句和从句均用一般过去时。
2、which用法：用作关系代词，可引导*性定语从句或非*性定语从句，引导非*性定语从句时which可以用整个主句作为其前行词，相当于and that,有时还可引导不定式短语从句。
三、侧重点不同
1、as用于一般现在时。
2、which用于一般现在时或一般将来时。

1. as引导的从句表示说话人的看法、态度、解释或评论
引导定语从句时，as仍具有“正如，像，由……可知”等意思，翻译时有时可不必译出。as定语从句常含有这些动词：see, know, hear, watch, remember, say, tell, show, expect, guess等，这类动词与as连用几乎成了一种固定搭配。as引导的此类从句可以置于句首、句中或句尾。如：
The famous magician Liu Qian, as we all know, is from Taiwan. 众所周知，著名魔术师刘谦是台湾人。
There is a net bar around here, as I remember. 我记得这儿附近有一家网吧。
As is often the case, girls like dolls while boys like guns. 女孩子喜欢玩具而男孩子喜欢*，这是常见的情况。
2. which引导的从句对主句所叙述的事情进行补充说明，表明事物的状态或结果
which此时指前面主句所提到的这件事，常译为“这一点，这件事”等。这时它所引导的从句与主句之间常含有并列、因果关系。注意，它引导的从句不像as那样位置灵活，它只能位于主句的后面。如：
He changed his mind again, which made us all angry. 他又改变了主意，这使我们大家都生气了。
She tore up my photos, which (=and that) upset me.她撕碎了我的照片，这使我很不安。
3. 在从句中作定语或介词的宾语时，要用which，不用as
Jenny might come, in which case I'll ask her. 詹妮可能会来，要是那样的话我就去问她。
She graated from a local middle school, after which she went to Beijing University. 她毕业于当地的一所中学，之后她去了北京大学。
4. 当从句的谓语动词是否定形式或含着一个复合宾语时，一般用which而不用as
He pretended not to know me, which I didn't understand. 他假装不认识我，这是我搞不明白的。
He admires everyone in his class, which I find quite strange. 他羡慕班里的每个学生，我认为太奇怪了。

"the same...as"与"the same....that"
两者都引导定语从句。that从句中说明的名词与the same修饰的名词是同一个。as从句中说明的名词与the same修饰的名词是同一类，而非同一个。
举例：
①This is the same pen that I lost. 这支钢笔就是我丢的那一支。
②This is the same pen as I lost. 这支钢笔跟我丢的那支笔一模一样。)
二：
“as”特殊定语从句中可以主谓倒装，“which”从句中则不能主谓倒装。
三：
句子作先行成分时：“as”特殊定语从句的位置较灵活，可以置于先行成分之前、之中。

1 as 引导的从句表示说话人对话语的看法，态度，解释或评论。
① as 表示“正如，像，由……而知，与……一致”等某些连词的语义。
② as 常用作一些动词的宾语（see , know , hear, watch , remember ,say ,tell , show …）这类动词与as 几乎成了一
种固定搭配。
③ as 从句可以放在句首（which 从句则不可以）
2 which 引导的非限定性定语从句对主句所叙述的事情进行补充说明，表明事物存在的状态或引起的结果。
① which 表示“这一点，这件事”（指前面主句所提到的），主句与从句通常要用逗号隔开，只能位于被修饰的句子后面。
② which 一般作从句的主语，这时它所引导的从句与主句之间常常含有并列，因果关系。
I bought my sister a big toy ,which delighted her greatly .
③ 在从句中作定语或介词宾语时，要用which
She might possibly come , inwhich case I’ll ask her .
④ 不能省去非限定性定语从句中的动词be 时，用which （反之，用as）
Jane told me shewon the match , which was a lie . ( was 不可以省略 )
As ( was )planned , we met at the airport . ( was 可以省略 )
⑤ 当从句的谓语动词是否定形式或从句的谓语动词带的是一个复合宾语结构时，一般用which ，而不用 as 。
You pretended notto know me , which I didn’t understand .
He admireseveryone in the class , which I find quite strange .
which→在定语从句中做主语或宾语→用来指物
① 这是你想要的那本书。This is the book which youwant.
② 我喜欢红色的那辆车。I like the car which is red.
③河边的那幢楼是我们的学校。The building which stands near the river is our school .
必须用which的4种情况：
(1) 当关系代词前面有介词时 Thisis the house in which he once lived .
(2) 引导非限定性定语从句
(3) 一个句子中有两个定语从句，为了避免重复，一个用which一个用that
He bought an American magazine that could give him so much Englishknowledge and which could help him
to kill time .
(4) 当先行词本身是that时 Theclock is that which tells the time .
as→在定语从句中做主语或宾语→用来指人或指物。
such…as… 如此像…，这样的像…，像…一样
the same…as… 相同的…，像…一样
①你们正在唱的那样的歌很流行。Such songs as you’re singing are popular now.
②我想使用和这里用的一样的工具。I want to use the same tool as is used here .
* the same…as… 和 the same…that… 虽然结构上相同，但有时句意却不同。（the same…as…指两物相似；the
same…that…描述的是同一物。）
① 这和我上周读的那本书是一样的。This is the samebook as I read last week .
② 这就是我上周读的那本书。This is the same book that I read last week .
* as引导非限定性定语从句，代表主句或主句的一部分所表达的意思（不能指代名词或代词），可放在句首，句中或句末，在从句中作主语或宾语。
① As is known toall , he’s the best student in the class .
② As we allknow , he studies very hard .
* as 引导的定语从句的常用固定表达法有：
as we all know 正如大家所知
as I can remember正如我所记得的
as often happens 这经常发生
as we expect 正如我们预料的那样
as you see 这一点你明白
as has been saidbefore 如前所述
